Peeps-Flavored Oreos Are Here, and They’re Turning People’s Poo Pink

A different kind of easter egg

Oreos loves itself some limited editions. From red velvet to candy corn to thin mint, half the fun is in buying a pack just to find out what they taste like.

But in the case of its Peeps-flavored variety, which came out a few weeks ago, users have discovered yet another surprise: It turns your poo pink.

OK, that’s not the whole story. It turns your saliva pink first:

But back to poo. Not everyone is seeing the bizarre side effect, which stems from the food coloring, FD&C Red Number 3, used in the painfully sweet cookies. It’s more likely to happen when you eat a lot all at once—a whole sleeve, suggests HuffPo, or even a pack:

The saliva and tongue transformation is less demanding. One or two cookies will do the job.

But the effect of both is weird enough that the internet is having a field day. (It probably doesn’t help that the Peep on the package looks almost like it’s guaranteeing results.)

Below, more reports from users, who mostly alternate between irritable and bemused.

On spit and bright pink mouths:

On rose-colored feces:

In a statement that is less contrite than factual, a spokesperson from Oreos explained the phenomenon in more detail.

The Oreo Peep limited-edition sandwich cookies contain a bright pink food coloring, FD&C Red Number 3. We use this ingredient in the product consistent with U.S. Food and Drug Administration (FDA) regulations.

Certain foods can temporarily color the tongue and inside of the mouth. This is common with brightly colored products such as ice pops, gelatins and drink mixes, as well as with certain fruits and vegetables, including beets and cranberries. Such foods can also temporarily color stool.

That comment doesn’t bode well for what we hoped, which was that Oreo—being the Super Bowl blackout darling—would find a clever way to turn the tide back in its favor, like Reese’s did in 2015.

That year, the latter released limited-edition candies shaped like Christmas trees, which the social landscape, in its infinite wisdom, found more fecal than festive. In response, Reese’s launched an adorable campaign against “tree shaming,” inspiring even more people to eat the stoolish globules.

Doesn’t look likely in this case.

Charmin, on the other hand, is having a wicked time:
